ROHM Sensor ICs

Ambient Light and Proximity Sensor ICs

ROHM ambient light sensor (ALS) ICs are designed to control the brightness of LED backlighted LCD displays, or LED lighting based on ambient light availability and brightness for optimum visibility and energy saving.

Hall Sensor ICs

ROHM's ultra-compact Hall ICs feature high sensitivity contactless magnetic field detection as well as positional detection on a single chip. The line-up inclludes 3 types of Hall ICs based on the detection method and type of output (bipolar, polarity discrimination, monopolar)

IR and Optical Sensor ICs

ROHM offers a wide selection of optical components including discrete components like photo transistors and IR-LEDs as well as integrated modules such as IrDA, remote control modules, tilt sensors and photo-interrupters. Compared to RF solutions IR based communication offeres avantages like high level of sequrity,more design freedom ( compatibility for future redesigning of set ) which makes them interesting for a wide range of applications.
